a tech start up that manages to survive despite having a bad business idea and substandard executive leadership. First used by an unnamed recruiter to describe an unnamed company. Ultimately it is a place that you would not want to work!

Recruiter: "where are you working now"
Candidate: "XYZ Company"
Recruiter: "that place is a shitnest"

The placement of several sections of toilet paper on and around a public toilet seat, layer upon layer, before sitting down to take a dump or piss, in a paranoid attempt to avoid non-existent toilet seat germs.

I went to go use the washroom at the office the other day and some asshole left his shit nest still assembled on the toilet seat. What the fuck am I supposed to do with his shit nest?

The result of using a "splashgaurd" or "shit raft".
Feces sinks downward, wrapping itself in a comfortable nest of toilet paper.

Highly fibrous or buoyant shits will remain partially exposed to the air in the center of the nest, allowing them to pollute the surrounding air quality, and penetrate the nostrils of others in the area.
